Mastering Compound Naming for Chemistry Students

 
Lesson: (Naming compounds)
 
Objectives:
To be able to n
ame compounds
Write the chemical formula of different
compounds
.
 
A 
compound
 is a substance composed of two or more elements combined in a
specific ratio and held together by chemical bonds.
 
Familiar examples of compounds are water and salt (sodium chloride).

Remember that
 some 
compounds consist of 
two different elements
.
(metal and non-metal)
 
1) Name the first element that appears in the formula.
 
2) Name the second element that appears in the formula, changing its ending to 
–ide
.

Remember that
 some 
compounds consist of 
two different elements
, 
one of them is oxygen.
 
1) Name the first element that appears in the formula.
 
2) Write oxygen, changing its ending to 
–ide
.

Some 
compounds are made up of non-metals only. To name these compounds, you need to
know the numbers of atoms of each element in a compound.
 
Prefixes are used to show how many atoms are present in each molecule.
 
Mono (or no prefix) – 1
Di – 2
Tri – 3
Tetra – 4

  1. Lesson: (Naming compounds) Objectives: To be able to name compounds Write the chemical formula of different compounds.

  2. Compounds A compound is a substance composed of two or more elements combined in a specific ratio and held together by chemical bonds. Familiar examples of compounds are water and salt (sodium chloride).

  3. Naming Compounds (metal and non-metal) Remember that some compounds consist of two different elements. (metal and non-metal) 1) Name the first element that appears in the formula. 2) Name the second element that appears in the formula, changing its ending to ide. Examples: AlF3Aluminum fluoride Magnesium Chloride MgCl2

  4. Naming Compounds Remember that some compounds consist of two different elements, one of them is oxygen. 1) Name the first element that appears in the formula. 2) Write oxygen, changing its ending to ide. Examples: Calcium oxide CaO Potassium oxide K2O

  5. Naming Compounds Remember that some compounds consist of three different elements, one of them is oxygen: 1) Name the first element that appears in the formula. 2) Name the second element that appears in the formula. changing its ending to ate. Examples: NaNO3 Sodium nitrate K3PO4Potassium phosphate

  6. Name the following compounds: KCl NaCl CaO MgBr2 CaF2 K2S LiBr Mg(NO3)2

  7. Name the following compounds: KCl - potassium chloride NaCl - sodium chloride CaO - calcium oxide MgBr2 - Magnesium bromide CaF2 - calcium fluoride K2S - potassium sulfide LiBr - lithium bromide Mg(NO3)2 - magnesium nitrate

  8. Compounds containing non-metals only Some compounds are made up of non-metals only. To name these compounds, you need to know the numbers of atoms of each element in a compound. Prefixes are used to show how many atoms are present in each molecule. Mono (or no prefix) 1 Di 2 Tri 3 Tetra 4 Do not use mono on the first element. CO2 carbon dioxide CO Carbon monoxide

  9. Compounds containing non-metals only Do not use mono on the first element. Molecule of compound made up of Name of compound 1 atom of sulfur and 2 atoms of oxygen 1 atom of sulfur and 3 atoms of oxygen 1 atom of phosphorus and 3 atoms of chlorine 2 atoms of nitrogen and 4 atoms of oxygen
